Our Expert Opinion on Suffolk Building Society 1 Year Fixed Rate Bond

Jonny PeaseCo-Founder, DepositScout

Suffolk Building Society's 1 Year Fixed Rate Bond pays 4.35%, which sits below the market average for fixed-rate accounts and 1.00% behind the category leader at 5.35%. The rate does beat August 2026 CPI of 3.1% by 1.25%, so your money grows in real terms, but if you can lock away between £1,000 and £500,000 for a year, OakNorth Bank's Fixed Term 12 Months at 4.96% or Atom Bank's 1 Year Fixed Saver at 4.90% are worth a look first. The main catch here is the usual one for fixed bonds: no access until maturity.
